METHOD FOR PREPARING AMIDE
-
Page/Page column 3, (2010/04/23)
The present invention provides a method for preparing amides, in which an amino acid ionic liquid is used as both a reaction medium and a catalyst to catalyze Beckman rearrangement of a ketoxime, so as to produce an amide. In the method, the rearrangement is conducted by catalyzing a ketoxime with an amino acid ionic liquid having the asymmetric property at a moderate reaction temperature during a short reaction time, so as to produce an amide without adding other catalysts such as concentrate sulfuric acid. The method has advantages such as avoiding corrosion in equipments with pipelines, the high conversion rate of ketoximes and the high selectivity of amides.

, (2008/06/13)
A novel series of substituted quinoxaline 2-ones useful as neuroprotective agents are taught. Novel intermediates, processes of preparation, and pharmaceutical compositions containing the compounds are also taught. The compounds are glutamate receptor antagonists and are useful in the treatment of stroke, cerebral ischemia, or cerebral infarction resulting from thromboembolic or hemorrhagic stroke, cerebral vasospasms, hypoglycemia, cardiac arrest, status epilepticus, perinatal asphyxia, anoxia, seizure disorders, pain, Alzheimer's, Parkinson's, and Huntington's Diseases.
